The rating event fires before widget rating. You can use this event if you'd like to track the rated values. You can cancel this event by returning false.

$(function () {
    // Set rating event handler function
    $(".selector").wijrating({
        rating : function (e, data) {
     
        }
    });
});

rating = function ( 
   e : jQuery.Event,
   data : IRatingEventArgs
) { };
